1. The correctness of an account can not be lawfully proved by the testimony of a witness that the same is “ a correct copy of the charges made on the books ” kept by her, when the witness further testifies that “ she knew nothing of her own knowledge” with respect to the account, and “only copied in the book entries given to her by [another] on slips.”

2. ■ As the magistrate erred in admitting against the defendants illegal testimony which was necessarily prejudicial to them, the superior court erred in not sustaining their petition for certiorari.

Judgment reversed.
